Vascularization of the Optic Pathway*
نویسنده
چکیده
WHEREAS from the myelo-architectonic point of view the chiasma is merely an organ of transit, this is not so from the vascular point of view; there seems to be a partial dissociation between the myelo-architecture and the angio-architecture. The vascularization of the chiasma has been investigated on the basis of 22 human specimens. The techniques used (dissection after fixation in 10 per cent. formaldehyde, injection of Indian ink, staining with benzidrine, and microradiography) have been discussed in previous publications (Francois, Neetens, and Collette, 1955, 1956; Fran9ois and Neetens, 1956).

Electrophysiological and Histological Study of Lysolecithin-Induced Local Demyelination in Adult Mice Optic Chiasm
Introduction: Demyelination is one of the main causes of neurological disability. It is the end product of numerous pathological processes, multiple sclerosis (MS) being the most common cause. More than 70% of the MS patients suffer from optic disturbances. This disease commonly affects the optic pathway, particularly the optic nerves and chiasm. Several attempts have been made to produce a ...

PURPOSE To characterize the topography of and the cellular processes that underlie vascularization of the human retina. METHODS The vasculature of human eyes obtained from fetuses ranging in age from 14 to 38 weeks of gestation (WG) was examined in Nissl-stained, whole-mount preparations and by anti-CD34 immunohistochemistry. RESULTS The first event in retinal vascularization, apparent befo...

متن کاملVascularization of the Optic Pathway
TEis problem has been of only moderate interest to research workers, and publications and monographs on the subject have been sporadic, though a few well-known names must be cited here (Leber, 1865a, b, 1872, 1903; Magitot, 1908, 1947; Behr, 1935; Wolff, 1939, 1940, 1948). The findings being very diverse, it seemed appropriate to try to find experimentally the normal vascular anatomy of the opt...
